Works great - but when I change to Edit mode, I can move an item and as soon as I drop it the circle showing that something happens does not stop. The control is not marked as supporting partial rendering.

Probably you get jQuery conflict. If DNN detect's that jQuery is already loaded, it will not load jQuery from your custom module. It will use core version, which was loaded first. Then if both library versions varies, your module can't do the job.
Are all packets returns HTTP 200 code?

When I leave the registration of jQuery and jQueryUI away, it is still working in View mode (which leads to the conclusion that those resources are already loaded), but it still does not work in Edit mode. Anyway, there are no different versions as I load the standard libraries, therefore it should not come to a "double" load.
